Chapter 10. Implementing Views > About this Chapter

About this Chapter

A view is a virtual table whose contents are defined by a query. Like a real table, a view consists of a set of named columns and rows of data. However, a view does not exist as a stored set of data values in a database. The rows and columns of data come from tables referenced in the query that defines the view and are produced dynamically when the view is referenced. In this chapter, you will be introduced to views and the various functionalities that they support. You will also learn how to create, modify, and delete views. Finally, you will learn how to use views to insert, update, and modify data.
